Here's a little something that has served me well over the years: If you want to really flatter a woman, compliment her feet (just make sure not to do it in a creepy way, and it's a fine line between friendly and creepy). I'm convinced almost all women have at least a mild foot fetish, it just manifests itself in a different way than the Rex Ryan-style fetish. Just look at how they are about shoes. There's a direct connection there, in my opinion.
On the original topic, though, yes, bad feet can be a huge turnoff. To use kidman's analogy, it be the same as if you met "a hot chick with a cute face, nice rack and ass" but she had really hairy arms. Some folks aren't bothered, but for others it's a make-or-break thing.
